Which statement by a client taking iron supplements indicates a need for further teaching?

The statement made by the client about planning to take their iron pills with coffee indicates a need for further teaching because coffee contains compounds that can inhibit the absorption of iron. Specifically, polyphenols and tannins in coffee may bind to iron and significantly reduce its bioavailability. This means that taking iron supplements alongside coffee could prevent the body from effectively utilizing the iron, which is essential for those who may be trying to correct iron deficiency anemia or increase their iron levels for other health concerns.

In contrast, the preference for juice (which is high in vitamin C) is actually beneficial since vitamin C can enhance iron absorption. Avoiding dairy products with iron supplements is also a correct practice, as calcium in dairy can interfere with iron absorption. Lastly, including iron-rich foods in the diet is an appropriate strategy to help improve iron levels naturally.
